Fix lint error & remove black

Related to #620

Update the lint script and configuration files to fix the lint error. And remove black because ruff replace it.

* **scripts/lint.sh**
  - Update the `ruff` command to use `ruff check` instead of `ruff`.
  - Remove the `black` command.

* **.github/workflows/lint.yml**
  - Remove `black` from the `Install dependencies` step.

* **.pre-commit-config.yaml**
  - Remove the `black` dependency.
